I'm reading some urology papers and came across one involving penis growth (Kim & Song, 2008); here's an intro passage that I'm confused about:
A total of 58 patients with constitutionally small penises, without chromosomal anomalies and gene-associated syndromes, intersex, and hypospadias, were included in this study. The average patient age at their first visits was 10 years and the average follow-up period was 2.2 years.
What's a "constitutionally small penis"?
I've read the paper in detail and I don't see where the authors distinguish between a small penis and a "constitutionally small" penis.
Would a "constitutionally small penis" be the same thing as a "micro-penis"? If not, then where do we draw the line?
